The portion size for a Smart Life pet feeder can typically be adjusted through the associated smartphone app. However, the exact portion sizes and the range of adjustment can vary depending on the specific model of the pet feeder.

Here are general steps on how you might adjust the portion size:

Open the Smart Life app on your smartphone.

Select the pet feeder from the list of connected devices.

Look for a setting related to feeding amount, portion size, or meal size. This is often found under a 'Feeding Schedule' or similar menu.

Adjust the portion size according to your pet's dietary needs. This is typically done by entering a number or moving a slider.

Save your changes.

Remember, it's important to consult with your vet to determine the appropriate portion size for your pet based on their age, weight, breed, and overall health.

If you're having trouble adjusting the portion size, or if you're unsure what the numbers in the app represent (for example, if it's not clear whether '1' represents 1 gram, 1 ounce, 1 cup, etc.), I would recommend referring to the user manual or contacting the manufacturer's customer support for assistance.
